Narrative:

I departed phx airport in a twin engine C414. I was the PNF and acting as the CFI, giving instrument instruction, to a commercial/multi/instrument rated pilot. We departed VFR from runway 26L (with a class B departure clearance) and were subsequently given a swbound turn and a VFR climb to 8500 ft (restr to 8500 ft). My student was flying (under the hood) and I was intently scanning for traffic. Even though I was trying to keep an eye on my student, and his track and altitude, I was very intent on looking for traffic in this busy airspace. When my scan got back to my student and his instruments, I noticed that he was approaching 8800 ft and had not started to level off. Just as I was about to say something, the controller called to remind him of the 8500 ft restr, and he immediately leveled off. The primary human factor element was my prioritization of my scan for other traffic over my attention to my student. In retrospect, I should probably have reminded my student of the importance (especially in class B airspace) of the altitude restr somewhat sooner, before we got close to it.

Title: INST TRAINING FLT LEAVING PHX OVERSHOOTS CLRED ALT.

Narrative: I DEPARTED PHX ARPT IN A TWIN ENG C414. I WAS THE PNF AND ACTING AS THE CFI, GIVING INST INSTRUCTION, TO A COMMERCIAL/MULTI/INST RATED PLT. WE DEPARTED VFR FROM RWY 26L (WITH A CLASS B DEP CLRNC) AND WERE SUBSEQUENTLY GIVEN A SWBOUND TURN AND A VFR CLB TO 8500 FT (RESTR TO 8500 FT). MY STUDENT WAS FLYING (UNDER THE HOOD) AND I WAS INTENTLY SCANNING FOR TFC. EVEN THOUGH I WAS TRYING TO KEEP AN EYE ON MY STUDENT, AND HIS TRACK AND ALT, I WAS VERY INTENT ON LOOKING FOR TFC IN THIS BUSY AIRSPACE. WHEN MY SCAN GOT BACK TO MY STUDENT AND HIS INSTS, I NOTICED THAT HE WAS APCHING 8800 FT AND HAD NOT STARTED TO LEVEL OFF. JUST AS I WAS ABOUT TO SAY SOMETHING, THE CTLR CALLED TO REMIND HIM OF THE 8500 FT RESTR, AND HE IMMEDIATELY LEVELED OFF. THE PRIMARY HUMAN FACTOR ELEMENT WAS MY PRIORITIZATION OF MY SCAN FOR OTHER TFC OVER MY ATTN TO MY STUDENT. IN RETROSPECT, I SHOULD PROBABLY HAVE REMINDED MY STUDENT OF THE IMPORTANCE (ESPECIALLY IN CLASS B AIRSPACE) OF THE ALT RESTR SOMEWHAT SOONER, BEFORE WE GOT CLOSE TO IT.
